By presenting a new logo that resonates with the new identity and quality of the most recent collections, Formex certainly also responds to feedback received by their community.

Offering 32 possible configuration options, Formex’ new REEF Automatic Chronometer is a versatile dive watch. The 42mm stainless-steel case with its distinctive shape provides both a functional guard for the screw-down crown and a stunning visual symmetry alike. A double gasket construction is designed and tested for 300 m / 1000 ft of water resistance. Mirror-polished bevels and brushed surfaces throughout create a unique balance between elegance and the brand’s energetic spirit.

The REEF’s unidirectional rotatable bezel is made of an extremely hard and scratch-resistant Zirconium oxide ceramic. The graduations and numbers are engraved by femto-laser pulsations. Each bezel takes 60 minutes of precision engraving to achieve its three-dimensional effect.

Machined gear-like indentations on the bezel’s edge allow a diver the ideal grip to safely set and monitor diving time and decompression stops. The 60 click action is responsive and smooth, yet offers firm and precise function of the bezel.

The sunray finished dial is manufactured at Formex’s in-house dial manufacture in the Jura Mountains. The gradient for the different colors is sprayed by hand. The REEF’s bold rehaut-style hour markers are also hand-applied and triangle shaped, pointing towards the broad hour and minute hands that share the same detailed beveled mirror polish and brushed top surface finishing.

Hands and hour markers as well as a capsule on the bezel’s zero marker are deep-filled with Swiss Super-LumiNova® BGW9that emits a long-lasting blue glow in dark conditions. Being able to read the time with absolute certainty is a matter of survival when diving.
